FBX not importing, no errors in console
The size of "amandaModel.fbx" is 4 kilobytes while "bullet1shell.fbx" is 17 kilobytes, that didn't seem right. I suspect the actual mesh geometry is not in the amandaModel.fbx but that was just a file where various models from files were linked into.

You can access the actual models by importing one of the animation files in the "animations" directory. Here I imported "amanda@idle.fbx".



The object relations aren't imported properly, so you have some setting up to do after importing.
